Create a new request by clicking on the New button again and selecting Request. You will be greeted by a new window:
Once again you will have an open box to type in a description in Markdown for the new Request. Fill it up whenever you please, as it will be available for editing any time you want. Set a brief but descriptive request name and select its Collection and click Save
You will see now a new Tab set for a GET Request. Change it to whatever you need by clicking the drop-down menu.
Fill in the request with its Url and, if needed, use the Headers and Body tabs at will. Don't mind the other tabs for now.
Note that you can and should use your {{environmentVariables}} now as it makes it simpler to read by hiding some information, leaving only what you need to see.
Click Send to test your Request. Your output should be right below.
If everything is good, click Save.
But... what if you need that API's response on another request?
